Watermark

This transformation lets you apply a custom watermark or logo to an image, with adjustable size and transparency. You can either apply a single watermark or tile the entire input image with watermarks.

The output image always has the same size and type as the input image. If the input image is black and white and the watermark image is color, the watermark image is converted internally to black and white by using its luminance channel.

An overlay is displayed on the input image to let you see where the watermark image will appear on the output image. If no watermark image has been specified yet, the overlay consists of a single control point, initially located in the center of the input image. Once a watermark image is defined, the overlay also includes a rectangle that corresponds to the outline of where the watermark image will appear in the output image. To reposition the watermark, drag the control point in the center of the rectangle.

Size

This slider determines the size of the watermark image. The value represents the width of the watermark as a percentage of the input image width.

Style

This control lets you select one of two watermarking methods.

Single -- this method applies a single copy of the watermark image to the output image at a location you specify by positioning the overlay on the input image.

Tiled -- this method paints the watermark image over the entire output image.

Watermark Image

Use this control to select the watermark image you want to use. Internally, the watermark image is converted to the same type as the input image.

Watermark Amount

This Amount Control lets you set the transparency of the watermark image or create an optional mask for the watermark image. By using a mask, you can create watermarks of different shapes or with partial transparency. If no amount mask is defined, the watermark is rectangular.

Tips

Make sure your watermark image has plenty of resolution so it won't break down when you apply it to a large, high resolution image.
